It’s hard to judge this because the stories are so divergent. One side has a kid with a genuine (not faked) concussion and a coach who, instead believing the kid’s faking, makes the kid go stand in a corner, literally, for hours.
The other side has a kid who, when punished for faking an injury by a few hours of “detention,” immediately lawyers up (and daddies up) and makes a court case out of it.
Time may tell who’s closer to right, I suppose.
The Boy Who Cried Wolf.
If he established a reputation as a faker, who’s going to believe him? Once personal credibility is gone, nothing you say can or will be trusted.
